|Component of Microsoft Windows|
|Introduced in||Windows 95 build 58s (as Cabinet)|
|Last included in|
File Explorer is the application responsible for the Windows user interface (shell) and the default Windows file manager. The first build to include it was Windows 95 build 58s, under the name of Cabinet for the shell portion and File Cabinet for the file manager part. It was a 16-bit program (
CABINET.EXE) in this build, and became 32-bit in build 73f (
CAB32.EXE). Build 189 is the first leaked build to rename Cabinet to Windows Explorer (
EXPLORER.EXE). During the development of Windows 95, several Shell Technology Previews were released for Windows NT 3.51, that brought the new user interface to the NT series. Internet Explorer 4 updated Windows Explorer with a new, web-integrated experience. Windows Vista saw major changes to Explorer, simplifying the UI somewhat, as well as removing features Microsoft thought were under-utilized. Windows 7 added Libraries to the Explorer experience. In Windows 8, Windows Explorer was renamed to File Explorer and received the ribbon UI. Windows 11 redesigned the file manager UI again.
History[edit | edit source]
Development[edit | edit source]
File Explorer was first introduced during Windows 95 development, but it did not start out looking like its final design. In early builds, Explorer was named Cabinet, the Taskbar acted as a folder, and the unified Start Menu was not present. It was instead divided into three separate menus, each providing a portion of the final functionality. The first menu (denoted by the Windows logo) acted as a system menu where you could access applications using the 'Run' dialog, manipulate windows and shutdown Windows. The second menu (denoted by a magnifying glass) provided Windows Search-like functionality. The last menu was the 'Help' menu where you could access the Windows documentation and get basic system information.
Windows 95/NT 4.0[edit | edit source]
The Explorer design included in Windows 95 used large icons for folders and drives, and had a menu bar at the top, which contained various options such as renaming and deleting files. By default, new folders or directories would open a new Explorer window, but this could be configured to use a single window with a toolbar at the top, which contained back and forward options. This toolbar was hidden by default, however. Context menus, triggered by right-clicking on various UI elements, now played a much bigger role than in previous versions of Windows.
Shell Technology Preview/NewShell[edit | edit source]
NewShell is an installable package that adds the new NT4 (alpha) shell to NT 3.51. Three builds of NewShell have been leaked so far; a very early build included with Windows NT 3.51 build 854.1, Shell Technology Preview build 1054 and build 1057. NewShell's UI is similar to that of Windows NT 4.0 build 1130.1. It causes the kernel version to jump to NT 4.0. A final version of NewShell was never released. Its purpose was to test the Windows 95-style shell on Windows NT so it could later be ported to the upcoming NT 4.0, appropriately codenamed "Shell Update Release".
Windows 98/Me/2000[edit | edit source]
Windows 98 included Internet Explorer 4 and substantially refined the Explorer UI to be integrated with Internet Explorer. The overall shell update was known as the Windows Desktop Update. Explorer windows now featured a bar at the left side containing information about the selected folder or file, this was known as the "Web view" and could be disabled in favor of the Windows 95-like experience. Various system folders would first display a warning page that the user had to skip in order to see folder contents. An improved toolbar, based on that of Internet Explorer, was also now shown by default, allowing users to easily navigate the directories much like they would navigate a website. Windows 98 also introduced Active Desktop, which allowed web content to be placed on the desktop. Animations were added to context menus, and title bars could now be customised with two-colour gradients. The taskbar received the ability to host various toolbars (removed in Windows 11), and a "Quick launch" section of shortcuts on the left side next to the Start button (removed in Windows 7). Windows Me added a minor enhancement to Control Panel, grouping the most frequently used settings into a category view. The classic icon view was still available, however.
Most of these changes were ported to the NT line with Windows 2000, and installing Internet Explorer 4 on Windows 95 or Windows NT 4.0 would bring over most of the changes as well if the user chose to install the Desktop Update. These changes and integration with Internet Explorer became highly controversial due to the inability of OEMs and end users to remove Internet Explorer (which was perceived as Microsoft trying to curb competition in the browser market), and were the subject of the 1998 antitrust case against Microsoft, settled in 2001.
Windows XP[edit | edit source]
Windows XP introduced major changes to the Explorer UI to make the experience easier and more intuitive for new users. A common tasks pane was introduced, but the old web view pane could be enabled with a registry tweak. The common tasks pane provided easy access to tasks such as deleting files, and it also provided quick access to other folders. A new Filmstrip view has been introduced, which provided quick previews of image files. A new Search UI was introduced featuring the Search Companion. This UI design would now automatically adapt to the selected theme.
A new Start menu was also introduced, featuring more items in the initial panel, such as recently used programs and additional links to various Windows components.
Windows Vista[edit | edit source]
Windows Vista saw many changes to Explorer. The common tasks pane from Windows XP was removed, and replaced by a new command bar at the top. The address bar was removed, and replaced by a new "breadcrumbs" bar that was easier to use than the previous UI. The left side of the window featured a navigation tree, providing access to user folders, but hiding other folders away in a "Folders" drawer. The Filmstrip view was removed and replaced by a new preview pane. Drives would show their free amount of space in a bar that would appear under the icon. The classic menu bar could still be enabled, and the navigation tree could be hidden.
The taskbar received a minor visual update, most notably in the form of the new Start button with only the Windows logo without the classic "Start" text. Windows Search was now integrated into the Start menu.
Windows 7[edit | edit source]
Windows 7 made minor changes to the Explorer UI. The icons in the command bar were removed, and all folders were now shown in the navigation pane as opposed to them being in a separate drawer. Libraries were added, which was a type of folder that would display the contents of the folders contained in it, similar to symbolic links.
The taskbar received a major upgrade, commonly known as the "superbar", including larger icons by default (though there was also an option to switch to small icons) and the ability to easily pin programs to it. This replaced the previous "Quick launch" functionality, available since Windows 98. Program buttons no longer display the program name by default, though this can likewise be enabled again in the settings. New context menus for program buttons with jump lists were added, and programs could integrate with the taskbar by showing current progress on the button in the form of a progress bar. A new "show desktop" button was added to the right side of the taskbar, which could also be used to quickly glance at the desktop by hovering over the button if the Aero Peek functionality was enabled.
Windows 8[edit | edit source]
Windows 8 replaced the command bar with a much more advanced Ribbon UI, which had been previously used in Microsoft Office since Office 2007. It introduced smart tabs, which would automatically appear when browsing a certain folder. Windows 8.1 later removed the ability to show Libraries by default, and added the user folders to This PC.
Windows 10[edit | edit source]
Windows 10 introduced updated icons and a new "Quick access" menu, which provided easy access to frequent files and folders.
Windows 10X[edit | edit source]
Windows 10X replaced the classic File Explorer with a new Files app, which would display files backed up to OneDrive instead of being stored locally on the device. The UI was based on OneDrive.
Windows 11[edit | edit source]
Windows 11 build 22000.51 revamped the classic File Explorer to feature new navigation buttons, rounded corners, new icons, new context menus and a new command bar to replace the previous Ribbon UI. The title bar and command bar also has Mica transparency effects.
